A framework for exploring strategies for building resilient communities.

Complex living organisms and natural ecosystems embody layered architecture. We live in human-made ecosystems that also embody layered architecture. Resilience is the ability of a complex system to maintain essential functions and system integrity when a severe disruption occurs. Disruptions always have local impacts and require local responses, even when they affect large geographic areas. Resilience must therefore be local and everywhere, and must permeate all the layers. This session offers a system-architecture approach to build community-level resilience in concentric layers. The first or central layer of the human-earth system is me, the individual person. Next is my household, then my block, my neighborhood, my city, my bioregion, my state, and so on. Each layer has its own resilience strategies, and what happens in one layer affects the other layers more or less, especially adjacent layers. All layers involve human interactions and thrive on social and economic interdependence.
